The BAFTA award-winning series that gets under the skin of the largest animals on the planet returns for a second series to reveal the anatomy of some of nature’s most successful predators: the Great White Shark, Lion, Tiger and Python.

Most wildlife documentaries show how animals behave, but by exploring their anatomy, veterinary scientist Mark Evans, comparative anatomist Joy Reidenberg and a team of experts show how these creatures really work.

Evolutionary biologist Richard Dawkins explains how such distinctive beasts have evolved to thrive in their environmental niches, while biologist Simon Watt gets first hand experience of the animals in action.

Highlights of the series include Joy Reidenberg coming face-to-face with Great White Sharks in a dramatic cage dive encounter, Simon Watt being squeezed by a live python, and the team making a dead lion roar by passing compressed air through its windpipe.
